UAC0184 runs a multi-stage phishing campaign using fake documents and shortcut files to trick users into execution. The attack abuses legitimate Windows tools like BITSAdmin and PowerShell to download and run malicious content. It uses steganography to hide malware inside image files, which is then extracted by a loader.
